... existence of positive and negative charges in subatomic particles (Atomic Theory). The following year, Thomson discovered the electron using a cathode ray tube. He also originated the idea that the electron had a negative charge (Atomic Theory). In 1910, Robert Millikan discovered the exact charge of the electron by using the oil-drop experiment. He won a Nobel Prize in this year (Millikan's Oil Drop Experiment ... ). During 1912, Niels Bohr theorized that electrons did not spin into the nucleus. The theory also stated that electrons orbit at certain allowed distances and atoms radiate e...
